Common Core: HSA-CED.A.2

Writing Equations with Two Variables from Word Problems: A-CED.2
How to write an equation with two variables to model a word problem?
Examples:

1. Mia sells small pumpkins for $5.50 each at her fall farm market. If she makes $1,125 in revenue this fall, what equation models Mia’s revenue?
2. Mikai’s pay-as-you-go cell phone company charges $0.16 per minute for calls and $0.10 per text message. If Mikai’s cell phone cost for one month is $196.80, what equation models Mikai’s total monthly cell phone cost?

Writing Equations to Solve Problems with 2 or 3 Variables (A-CED.2)
How to write equations to represent a situation with two or three unknowns and how to use these equations to solve problems?
Use systems of equations for more than one unknown.
Solve systems by graphing or by using algebra (substitution or elimination).
